I have had paper thin nails my whole life that I simply could not grow. They would just bend, peel and chip away. I tried just about everything, and a last ditch attempt was when I saw this. Lo and behold, however, it worked wonders on my nails. I used it as a standalone coat or as a base coat for colour, and my nails when from thin and useless to hard, strong and beautiful after just a few weeks of prolonged use. I would highly recommend it, especially for anyone that has nail issues!
